ABSTRACT:
The interrupter includes and apparatus having a pair of oppositely rotatable, spring loaded, sharp edged elements positioned above a pair of wire fuses. Such fuses complete the current path in respective conductors of a two conductor electrical appliance power system. Each edged element is retained by a latching tension of the other fuse, so that opening of either of the two fuses releases the element above the other fuse, causing such element to rotationally descend and apply a cutting force to the other fuse and thus assist in its opening to assure that both conductors of the power system are opened in an immediately successive manner in response to a current overload.
